SIDE FRAME FOB CAR-TRUCKS.

Patented Aug. 29, 1916.

Application `filed May 19, 1915. Serial No. 29,181.

To all whom it may concern: j

Be it known that I, THOMAS F. TOMLIN- son, a citizen of the UnitedStates, residing at Norfolk, inthe county of Norfolk and State ofVirginia., have invented certain new and useful Improvements in SideFrames for is 'a l side frames which are detachably associated with thetruck, to permit expeditious removal ofthe frames, although positively.

retaining the axis from Adisplacement during movement.

.A' further object of the invention is to provide side iframes whichwill permit removal of the journal boxes, but will positively preventaccidental displacement of the journal boxes, should the hinged ends ofthe frames become accidentally disengaged, at the same time, requiring aminimum elevation in order to remove the journal boxes from the carframe.. l

Other objects as well''as the nature, characteristic features and scopeof my invention-will be more readily understood from the followingdescription taken in connection with the accompanying' drawings and.pointed out in the claim forming a part of this specification. l

Referring to the drawings: Figure 1 is a side elevational view -of aside frame constructed in accordance with my invention one of the hingedends thereof being swung downwardly in an open position, Fig. 2 is adetail elevational fragmentary view of a side frame constructed inaccordance with my invention, illustrating the application of the samewith a car wheel, axle and journal box, said axle and journal box beingshown in section, Fig. 3 is a detail enlarged perspective fragmentaryview of one of the side frames used in this invention, Fig. 4 is aytransverse sectional view of a side frame constructed in accordancewith my invention, illustrating the application of the same, and Fig. 5is a plan view of the bolts used in this invention.

In the drawings, in order to illustrate the application of thisinvention, car wheels '1 are provided which are rotatably mounted uponaxles 2 in the usual manner, the free ends of the axles 2 having journalboxes 3 associated therewith. 'Flangcs 4 are formed upon said journalboxes 3, andare arranged in spaced-apart relation to provide an annulargroove 5 in each of said journal boxes, as shown to advantage in Fig.il.

' My improved side frame is generally designated in the drawings at 6and comprises a skeleton body having a supporting column 7 formedapproximately midway its ends and in which a longitudinally extendingrecess is formed to receive the truck bolster 8 and a. spring plank 9 ofthe usual configuration, the latter being hel(1 in spacedapart relationthrough the medium of coil springs 10. The terminals of the frame, areprovided with hinged portions 11, each of said portions comprising anangle iron, one end of which is bifurcated as indicated at l2 forpivotal engagement with the lower end of the body of the frame G, theopposite end of said right-angled portion being reduced as indicated at13 and mounted bctween the branches of a bifurcated portion 14 of thebody of the frame 6. Vhen the angled portion 11 on each end of the bodyof the frame 6 is in alocked position, an oblong opening 15 is provided,adapted for the reception of a journal box, the frame Gbeing held fromdisplacement on the journal boxes in either direction, in view of theflanges 4, heretofore described. The angled portions 11 are held inengagement with the frame 6 by bolts 16, the latter being held fromdisplacement by cotter pins 17 although it is to be understood that anyof the bolts may be removed, if so desired,and when one bolt is removedon either end, the other bolt will provide an axis, so as to permit theangled portion 11 to be swung either upwardly or downwardly in avertical plane, thereby permitting the journal boxes to be removed whenso desired. It is customary, however, to permit the angled portions 11to swing downwardly, since the weight of these portions will cause themto gravitate to the farthest point of movement, thereby permitting 'llithe journal boxes to be removed when the frame (3 is very slightlyelevated, it being, of course, necessary to elevate the frame in viewofthe bifnrcated ends 14 of said frame, said bifurcated portions beingturned at right angles to the longitudinal axis of4 said frame, andserving in the capacity of abutments, so as to prevent the journal boxesfrom being casually displaced, should the angled portions 11 of saidframes be acciertheless movement is limited, in view of the fact thatsaidportions swing in the path of the side frame to abut the latter,since the lower marginal edges 111 of the angled portions, adjacenttheir pivot points, will engage the shoulders 112 of the side frames asshown to advantage in Fig. l.- The shoulders 112 are formed -by reducing,the ends of the side frames, as indicated in Fig. 3, said reducedportions being pivotally ar,-

'ra-nged between the branches of the bifurcations 12. By thisconstruction it will be y impossible for the angled portions 11 to swinginto contact with the rail ties in the event of casual disengagement ofthe upper ends of the angled portions, since the latter will not bepermitted movement below a plane on a parity with the top of the rails.

It will be understood that the above del scription and accompanyingdrawings comprehend onl the general and preferred einbodiment o myinvention and that various minor changes in details of construction,proportion and arrangement of parts may be A side frame for car trucksincluding a body having openings ladjacent its termi-v nals toaccommodate journal boxes therein,

`a portion of each terminal being removed to permit engagement of thejournal boxes in `vsaid openings and removal of the same therefrom, theterminals of said portions being formed to engage corresponding parts ofthe body, each removable portion lbeing operable on either of its endsas an axis, portions of said body lying in the path of movement of 'saidmovable portions to limit their downward movement to a plane on a.parity with the parts of said frame which engage the upper terminals ofsaid removable portions bemg depended to provide abutinents forpreventing casual displacement of the side frames in the event ofdisplacement of said movable terminals.I

In testimony whereof I ax my signature in presence of two witnesses.
